The RD-80SA is the industry’s first multiple instrument and capable of being measured response time,
screen flicker, luminance, chromaticity and color temperature.
Recently, the demand for the 3D TV has increased. There is one of important evaluation items to measure a cross-talk.
It is one of the factors that greatly affect the performance of 3D display.
This product is most suitable for measurement a cross-talk of 3D display.
FEATURES
- Response time, luminance, and chromaticity can be measured while collimating.
- As small as 0.04cd/m² difference between two lights can be detected.
- Small crosstalk signal on the sequential 3D display can be measured.
PRINCIPAL USE
- Detection of crosstalk on Sequential 3D display.
- Detection of response time, screen flicker, and Gray-to-Gray of FPD.
- Measurement of luminance, chromaticity and color temperature of FPD and LED lighting.
